I don't see either.  Only the last two bits of topic_set_state seem to
do anything out of the ordinary, and I have applied the parts of
topic_set_opts that were posted in a previous patch to topic97_override
with no effect.  Aside from that there isn't much different.  I'll check
pcmcia-cs without modifications again to ensure that the difference
really is in that area.

It didn't hurt anything, but had no observable effect on the strange
socket state flags, the nobody cared IRQ, or the sluggishness on eject.

Yes, at eject, the system at first seems sluggish (hang-run-hang-run),
and then hangs altogether for 15-20 seconds, after which I hear the
pcmcia acknowledgement beep.
